I think building trees of the possible expressions as a couple of other
people have suggested is simply a more structured way of doing what
you're currnetly doing.
Right now you're throwing darts at the problem space, and hoping that
the next one point you hit will be a more optimal solution.
If you enumerate all the expression trees you are just ensuring you
don't miss any solutions.
I think the algorithm/hueristic I just posted should get you to the
answer quicker though...
